Because the fitness center may not have a boiler installed, hot water needs to be purchased from outside. The cost of installing a boiler is not small, and there is still room. If there is no need to install it in the general gym, but there is no other way to have a lot of hot water, so I choose to buy it.

Boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with certain heat energy. The original meaning of a pot refers to a container for holding water heated on a fire, and a furnace refers to a place where fuel burns. A boiler consists of two parts: a pot and a stove. The hot water or steam generated in the boiler can directly provide the heat energy needed by industrial production and people's life, and can also be converted into mechanical energy by steam power devices or converted into electrical energy by generators. Boilers that provide hot water are called hot water boilers, which are mainly used in life and have a small number of applications in industrial production. Boilers that generate steam are called steam boilers, usually referred to as boilers for short, and are mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.
